$\varphi$-contractibility and $\varphi$-Connes amenability coincide with some older notions

Functional Analysis 2017-06-21 v1

Abstract

It is shown that various definitions of φ\varphi-Connes amenability as introduced independently in \cite{Gh-Ja, mah, Sh-Am}, are just rediscovering existing notions and presenting them in different ways. It is also proved that even φ\varphi-contractibility as defined in \cite{Sangani}, is equivalent to an older and simpler concept.
